Race condition when clietn and namenode start block recovery simultaneously ---------------------------------------------------------------------------
Key: HADOOP-3503 URL: https://issues.apache.org/jira/browse/HADOOP-3503 Project: Hadoop Core Issue Type: Bug Components: dfs Affects Versions: 0.18.0 Reporter: dhruba borthakur Assignee: dhruba borthakur When a client detects a error while writing to a block, it starts the generation-stamp-protocol to remove stale replicas. At the same time, if the namenode experiences a lease expiry event for that file, the namenode starts the generation-stamp-protocol for the same block. Now, the client and thr namenode ping-pongs trying to stamp the block replicas. This ping-pong can continue for a long time. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
